If 8Chan was a breeding ground for Islamic Extremists would people be okay with still existing?

Strangely enough, most people who find censorship ideologically palatable consider Jihadists a more sympathetic group than Incels. Note that ISIS beheadings have been subject to far less censorship than the Christchurch shooter's propaganda, for example.

I make a factual claim you can investigate on your own. Perhaps your findings will surprise you. As an aside, I recommend engaging with people you disagree with politically to understand their motivations and opinions. Much of political discourse is superficially ridiculous, but almost everything can be made sense of and appreciated once you get a view of the whole picture. Good luck.
